Original Abstract

The article is devoted to the development of vacuum insulation materials using non-traditional core materials. At the Faculty of civil engineering, Brno University of technology, research is ongoing in cooperation with the Slovenian company Turvac in the field of development and study of the behaviour of environmentally-saving core insulators for application to vacuum insulation panels. These are primarily organic materials based on natural or waste polymeric fibers. This article describes the results of research activities on this issue where test samples of insulation from primary or recycled cotton and polyester fibers obtained from textile recycling were tested. The objective was to verify the properties of the developed insulators under extremely low pressure and thus the possibilities of their potential use as core insulators in the vacuum insulating panels. On the basis of the results found on both core materials and prepared vacuum insulating panels, it can be stated that core materials based on primary and recycled polyester fibers represent a great promise for the future. By reducing the pressure in the structure of these insulators, thermal conductivity is reduced to the level typical of high-quality conventional core insulators (e.g. based on glass wool). These materials exhibited very good thermal insulation behaviour, depending on pressure and time.
